My research interest is on the evolution of acoustic communication in marine mammals. I use a number of methods including phylogenetics, data mining, bioacoustics, and behavior to study how acoustic signals evolved in these animals and to understand how they respond to changes in their soundscape. I am also interested in the application of remote underwater recording systems to study various scales of geographical and temporal variations in soundscapes and how these changes may affect the acoustic communication spaces of marine organisms that rely on sound for the survival and reproduction.

Habitat loss, overexploitation, and increasing noise levels are threatening the soundscape of many marine organisms, including marine mammals. A significant part of my research career is to use monitoring data to address conservation concerns on marine mammals, provide training, and develop awareness and outreach activities for the general public.

Teaching is an important part of what I do. I teach a number of courses including general biology, zoology, acoustic communication, evolution, and marine mammal field biology.

Studying marine soundscapes

In partnership with Conservation International Costa Rica, CIMAR-University of Costa Rica, Panacetacea, and the Ministry of Environment (Mi Ambiente) Panama, Dr. May-Collado is leading the project Ondas-Costa Rica and project Acustica Panama which main goal is to document the marine biodiversity using sound as a cue for species richness. The project also seeks to understand the impact of increasing noise levels associated to boat traffic to migratory species like humpback whales, and resident species of dolphins and fish. The project uses three models of underwater acoustic recorders to capture the soundscape of three marine habitats and online tools from ARBIMON II to catalog and analyze the information. For more information go to Project Ondas/Project Acustica.

Studying dolphin acoustic response to dolphin watching boats

I am co-advising graduate student Betzy Perez (McGill-STRI). She is studying how bottlenose dolphins from Bocas del Toro, Panama respond to dolphin watching boats. She is collecting skin samples (Permit MI AMBIENTE #SE-A-75-17) to measure stress hormone levels and deploying two RUDAR-mk2 underwater recorders to study how their acoustic behavior changes throughout the day in two locations that vary on boat traffic.
